I seem to have lost connectivity to AS 2828/XO
communications. I can't
get through to anyone on the BGP team at XO either. Anyone
else
experiencing this? Reply just to me, don't need to hold up
thread time.

Hi,

For those who may be interested, you can see how this outage
was perceived by routeviews' peers at LINX, using Rcat at http://rcat.rd.fran
cetelecom.com/


Set the following options: 

starting date: 2008-02-26 11:30:00
ending date: 2008-02-26 11:40:00
time zone value: Etc/GMT-6
logical query: ori2828


It's event: RV_LINX_2008_02_66828


It shows that the different routeviews' eBGP peers at LINX
have announced to the trace collector their path to join
AS2828 had become unavailable at about 11:28.

More precisely, it shows (when displaying the path
exploration* undergone by the eBGP routers connected at
LINX) that prefixes 205.159.169.0/24 and 63.244.0.0/16
(originated by XO) were unreachable between 11:29 and 11:47.


What is more, it also shows that prefixes from 15 ASs behind
XO (mostly customers) were also impacted by the outage (some
only switched to another path but some also experienced
unreachability between 11:29 and 11:47)

Finally it shows that at 11:47 all the peers at LINX
reconverged to the path they were using before the outage.


It can also be noticed that Rcat had indeed identified
AS2828 as the originator of this outage, which agrees with
the core router failure claimed by XO (as explained at
outagesisotf.org )


Best
